Expandable chuck / flange-mount - MSK-TM series

The MSK-TM series by IBD Wickeltechnik GmbH is an expanding chuck or flange mount EMF which is expanded through axial pressure. The unit is supplied through the means of the core going into its chuck. Each unit comes with a standard design that can accommodate core diameters such as 70, 76.2, 100, 127, 150 up to 152.4 mm. Using this tool, it entirely eliminates the core damage regardless of what it is being made. May it be made with paper, fiber, plastic, aluminium or steel, its positive torque gives the unit a responsive grip which prevents costly core slippage and lowers maintenance cost.

Expandable chuck - ø 5 - 400 mm | SP

With the SP System, the clamping sleeves are compressed in the direction of the force by introducing an axial force, which causes them to expand radially. This simultaneously eliminates the clearance between the clamping sleeve and the workpiece, and between the clamping sleeve and the main body. The workpiece is clamped.

Depending on the clamping device and the design of the clamping sleeves as well as the workpiece tolerance, concentricity deviations up to 0.002 mm can be achieved with the SP System. Because of this high level of precision, the SP System is also used for tool clamping in addition to workpiece clamping.

Expandable chuck - ø 5 - 400 mm | SZ

By introducing an axial force, a split collet is expanded radially over a taper. This coincides with an axial movement of the collet. The workpiece is clamped.

The SZ System is used when the clamping basis of the workpiece to be clamped is short, or if the diameter to be clamped has a very large tolerance.

Expandable chuck - ø 5 - 300 mm | SH

The SH Hydraulic Clamping System is a closed system that is filled with hydraulic fluid. By introducing force using a piston, pressure accumulates in the system. This widens the thin-walled expansion zone radially and effects workpiece clamping.

The SH System is particularly suited for use in very tight spaces. The hydraulic system facilitates the clamping of long, thin-walled workpieces, or several identical workpieces at once.
